Not true since 4.x since only libc_r did this. Since FreeBSD 5.x, the default thread libraries (libpthread/libkse, and libthr) do not use signals for their implementation. Under 5.x and subsequent, just compile and link your program normally (use -pthread or -lpthread when linking) and you will get the default thread library (not libc_r, which has been deprecated in 7.x/current). -- DE
